Subject: [PATCH 00/27] Permit filesystem local caching [try #2]
Date: Wed, 23 Jan 2008 17:20:39 +0000 [thread overview]
Message-ID: <20080123172038.11107.86025.stgit@warthog.procyon.org.uk> (raw)
These patches add local caching for network filesystems such as NFS.
The patches can roughly be broken down into a number of sets:
(*) 01-keys-inc-payload.diff
(*) 02-keys-search-keyring.diff
(*) 03-keys-callout-blob.diff
Three patches to the keyring code made to help the CIFS people.
Included because of patches 05-08.
(*) 04-keys-get-label.diff
A patch to allow the security label of a key to be retrieved.
Included because of patches 05-08.
(*) 05-security-current-fsugid.diff
(*) 06-security-separate-task-bits.diff
(*) 07-security-subjective.diff
(*) 08-security-secctx2secid.diff
(*) 09-security-additional-classes.diff
(*) 10-security-kernel_service-class.diff
(*) 11-security-kernel-service.diff
(*) 12-security-nfsd.diff
Patches to permit the subjective security of a task to be overridden.
All the security details in task_struct are decanted into a new struct
that task_struct then has two pointers two: one that defines the
objective security of that task (how other tasks may affect it) and one
that defines the subjective security (how it may affect other objects).
Note that I have dropped the idea of struct cred for the moment. With
the amount of stuff that was excluded from it, it wasn't actually any
use to me. However, it can be added later.
Required for cachefiles.
(*) 13-release-page.diff
(*) 14-fscache-page-flags.diff
(*) 15-add_wait_queue_tail.diff
(*) 16-fscache.diff
Patches to provide a local caching facility for network filesystems.
(*) 17-cachefiles-ia64.diff
(*) 18-cachefiles-ext3-f_mapping.diff
(*) 19-cachefiles-write.diff
(*) 20-cachefiles-monitor.diff
(*) 21-cachefiles-export.diff
(*) 22-cachefiles.diff
Patches to provide a local cache in a directory of an already mounted
filesystem.
(*) 23-nfs-memleak.diff
(*) 24-fscache-nfs.diff
(*) 25-fscache-nfs-mount.diff
(*) 26-fscache-nfs-display.diff
(*) 27-fscache-nfs-persb.diff
Patches to provide NFS with local caching. The fifth of these patches
makes caching configurable per superblock.
I've fixed some current->fs[ug]id conversions as pointed out by Jan Harkes.
I also fixed patch 14 (fscache-page-flags.diff) to make
wait_on_page_owner_priv_2() use PG_owner_priv_2 rather than PG_private_2.

A tarball of the patches is available at:
http://people.redhat.com/~dhowells/fscache/patches/nfs+fscache-28.tar.bz2
To use this version of CacheFiles, the cachefilesd-0.9 is also required. It
is available as an SRPM:
http://people.redhat.com/~dhowells/fscache/cachefilesd-0.9-1.fc7.src.rpm
Or as individual bits:
http://people.redhat.com/~dhowells/fscache/cachefilesd-0.9.tar.bz2
http://people.redhat.com/~dhowells/fscache/cachefilesd.fc
http://people.redhat.com/~dhowells/fscache/cachefilesd.if
http://people.redhat.com/~dhowells/fscache/cachefilesd.te
http://people.redhat.com/~dhowells/fscache/cachefilesd.spec
The .fc, .if and .te files are for manipulating SELinux.
